Running TYL with 2.01+

[isfacat]

Greetings. New poster, flames welcome.

Just recently, I discovered about Fanjita's GTA eLoader for 2.01+ PSPs. I tried it. It worked like the rest of the people.

However, when I installed TYL 0.2c, the emulator starts off perfectly. After loading a ROM file, it then hangs. Thinking it might be the ROM, I tested it out on my computer with zSNES. All of them work properly.

I installed TYL 0.3 and did the same process, and it works. I've already gone back and taken a look at the speed compatibility issues with some ROMs, seeing how I can get most of them up to 60FPS, which is very hard, considering running 2.5 on my machine (Yes, stupid me).

If and when 0.4 is released, do you think that you might have better support for 2.0 and 2.01+ machines? I do realize the ME system on the latest version is awesome, but I would like to see some further support/development in assistance with 2.0+ PSPs.

Just my two cents.

By the way, guys? Good job on the emulator. At least I can get my Super Punch-Out fix during work.

I agree, a lot of people upgraded to play 2.5 psp games, so it shouldn't be their fault they can't get the same speed as someone with 1.5 version. I think making ME which only works on 1.5 work better won't really make people want to use this emulator more.

[disturbed19]

too be honest its too bad for ppl with 2.0+ bcuz im pretty sure its more made for 1.5 users, bcuz yoyo has 2 1.5's and laxera has 2 1.0's, i dont think they would take the chance of upgrading there psp's just to work on 2.0 and up. so too bad for ppl with 2.0+. i dont think its a good idea to threaten them by saying ppl wont want to use there emulator.

[gillberg]

I'm just saying if they got it to work better with 2.0+ it would be more popular.

[brent2k6]

i have 2.1 firm and im glad and greatfull that TYL team has made their emulator work for 2.0+, and for the other firm's.

[disturbed19]

well i didnt mean it in a bad way, but i think its extemely popular already, but possibly future releases may support 2.1+, but that would be totally up to yoyofr and laxer3a. so u never know.

Hi,

In my case I dont know how things will be going with PSP in the future.
For the moment we have TWO versions.

We will try to support and help everybody as much as possible, but we will never impact the quality of people having PSP 1.0 / 1.5

Our goal is to have the emulator that give the best perf for your hardware.
There is no point in a slow emulator...

Now if because of 2.0+ system, we have to do a "little" tweak to have multiple version. It is fine.
But if we have to change to the point that 1.0 and 1.5 do not benefit from the max performance we will not do it.

If you are really keen about a given platform, everbody knows that you should buy the first lof of hardware stuff as you will benefit from software implementation miss from makers.

I bought the PSP the first month of release... And waited 4 months until the "Hello World" program was possible.

[isfacat]

Well, I do appreciate the ROM tweaks you have implemented into TYL. With a few of my games, they run at 60 FPS.

The only ones that I really can't get running properly are Final Fantasy 6 (During battles, FPS drops to 20 or less. On the Main World screen, I'm getting 55-60 FPS) and Chrono Trigger (Same deal).

The rest, of my small stache, have no complaint.

Is it because of running the 2.0+ version of the emulator that causes this, or am I just completely missing something altogether?

[laxer3a]

Yes, if you had a 1.0 or 1.5 PSP, you would be able to use the second CPU (called ME) for homebrew, thus allowing TYL 0.3ME to run faster than the basic 0.3 version.

It is something that is limited by the PSP security hole itself, and we have nothing to do with it.

So yes, we will try our best to satisfy 2.0+ user too, but our focus will be to improve the global spec, which means that 1.0 and 1.5 is most likely to have superior version of the emu that 2.0+
And it is not our choice, but the choice given by the PSP itself.

Of course, if new feature can be compatible for both platform we will do it.

[laxer3a]

Yes we do know :-)

Now actually people that wrote some article are mistaking :
Media Engine
and
Virtual Mobile Engine

ARE TWO DIFFERENT CHIPSET.

ME is a second MIPS CPU (like the main cpu except it does have some limitation (cant access the VRAM, cant call system functions, no VFPU like the main cpu)

VME seems to be a mix between a DSP (CPU customized for computation) and a FPGA.
This second chipset seems to not be available even to official devellopper.

PS : I can see that you have a lot of time to spend doing nothing... You should go outside and get a life, or may be learn usefull stuff :-)
PPS : The kind of info we want, we can guarantee that you will not find it over the internet. And if so, definitly not with Google !

[word]

Burn!!!

[laxer3a]

Now the funny stuff is that the post between my posts have disappeared :-)
I dont think that Yoyo / Tinus or I would delete... Hey guys !!! Assume what you are saying here.
Dont delete after you got flamed. It is quite childish...

If I post comment, it is for everybody's benefit... not to reply to a ghost message.

PS : and it start to be way off topic.

PPS : I put again the link that was here before :

[disturbed19]

haha, ur a funny guy. u didnt have to be rude about it,it was the weekend when i put up those posts and i had nothing else to do that night, so i thought id try help a lil, then in return i get a rude reply saying i should get a life and learn something useful. i find that a little childish. i just decided to delete my posts because u made me look like a fool.

[corona]

If you act a fool, then be man enough to keep the post up for the rest of the world to veiw and enjoy.
None of us know you personally, so there is no reason to be so defensive of your posting messes.
We've all made mistakes with posting messages on the net, and you are certainly not going to be the exception.
For the sake of the world, let us laugh at your stupidity.

[disturbed19]

so its stupid to try help out?

[Cheeezy]

what you gotta do is......

find a PSP developer that helped create the PSP and program it and such. sneak him/her into a back alley and beat the information out of them that you need to know.

[laxer3a]

Disturbed, sorry if I offended you.

Just that people have to assume what they post. If everybody was deleting his own messages after other people wrote comment, the boards would really be a big mess and unreadable.
This is why I would really call that a childish attitude.

Now I put back the link, because some people may find these slides interesting. (they are worth a reading anyway.)

Now about the help, thanks for the "feeling". But please notice that the technical problem we are facing now are way beyond the fact that a chip is running at 333Mhz or using silicon in a 90nm fab process. And it is something that you can probably figure out yourself by reading it before posting. This is why I bumped into your messages.

Was it written on the slide "take care of doing this and that when using the ME and CPU at the same time ?" No... So why this would have helped us ?

I think it is good to propose your idea to people that spend their time looking at the problem in a deeper view.(often new ideas emerge from new ways of looking at problems : "think out of the box") But not by just throwing a book to somebody else.

I am not against help... I am also open to any discussion, but you must do it in a mature attitude (=look at the source code / propose concrete technical idea).

[Cheeezy]

so exactly how many processors does a PSP have?

[disturbed19]

alright, i understand man. thanx for the post i appreciate it. i wont delete any more of my posts. ;D

[kaosmaster]

Like an idiot i didnt read the forum rules, but here we go.
I currently own a 2.5 psp(white) and a psp 1.0(black) because i have nothing better to do with my money. And i must admit i love TYL's work, but of course, i rather play emu/roms on my psp white rather than black, because.. black sucks. So using the Gta Eloader hack, i stumbled across a program emu(snes) that actually ran properly (uo_Snes9x_002y32) and well.. its decent. It can't run like tyl's since the creator whos japanese, and only can speak in japanese, hasn't updated this version since Aug, 2005. Now.. that makes no sense, aug 2005? when the psp 2.50 update come out? and the gta hack? (i got the white psp@ dec 2005, so i have no clue) And rumor has it, this also works in 2.6.
People have demanded that TYL and UO to join together and actually make an EMU which works properly with 60fps rather than 10-20 fps in 333mhz mode. It would definately be appricated.
this forum is 2 days old since the last post, hopefully someone will read this =(
and this is my first day posting here, if i did anything wrong please don't own me -_-*

[Cheeezy]

wow you need a big slap in the face

[weenermcwang]

Here guys, I have a link that will help you out. You should be able to find out everything you need to know about the inner workings of the psp so you can make a super awesome new version that will run at a million fps.

www.sony.com

YAY! I'm helping!

[Cheeezy]

if it was a million fps then you wouldnt be able to tell waht was going on cuz it would be going to fast

im pretty sure these guys have done plenty of research and know very well what they are doing.

I still think what we really need is to find a PSP dev and sneak him into a back alley and beat the information out of him

[laxer3a]

Oups, I missed this thread :
cheeezy>> PSP got 2 CPU (CPU + ME) + 1 GPU + VME (super dsp) + and some hardware for making bip bip :-)

kaosmaster>> Y emu is a porting of the 1.43 code of Snes9x based on "bifuteki"'s version.
TYL is based on the 1.39 core of Snes9x , which is LESS compatible with some games BUT FASTER in average.

Moreover, Y focused mainly on detail feature and never spent time modifying "core" stuff.
I met him once (= real life) but he was not motivated to do his emu anymore (sept. last year)
Basically because of the nature of his port (using less feature of the PSP) his emu is able to run on more platform without any issues.
Now, Y version is quite slow compare to TYL in many cases...

That's fairly old news man.
Yoyo had a chat with Y about that a long time ago. All that happened was they argued about core emulation for a little while, then it ended. It wasn't spectacular, and the work on uoSnes9x was less than spectacular.
The only nice thing about uoSnes9x was, I must say, the lovely cheat code support that was implemented right from the beginning.
Ive always wondered why Yoyo never just bummed the code for cheat support off of Y, but I guess I really don't care enough to mention it on the board until now.
Meh.
